Dear all,
I would like to apologize for making quite a few mistakes during the lesson just now. Was really lethargic (I know most of you were tired too), admit that I couldnt fully focus...:S
I've tried my best too...:) I know many of you were! thanks for giving me the attention!!:D
Please alert me next time if you realize I said something wrong, k? Thanks Ahmad and Zul for doing so!:) Appreciate that!
Regarding the action of activator proteins-->when it binds to enhancer--> cause the DNA to bend (by DNA bending proteins), recruit the mediator proteins to STABILIZE the Transcription Initiation Complex. After the initiation, the bent DNA would revert back, only RNA polymerase would continue with the elongation of RNA strand. Therefore, many RNA polymerases could transcribe a gene at the same time.
(let me know if you still cant get it...)
